The member that opening/closing portion 6 is shunk by free wxpansions such as fluorubber, silicone rubber, EP rubbers forms.Such as Fig. 2, shown in Figure 4, opening/closing portion 6 between peristome 7c and the 2nd control water 5a of section, forms for example crooked shape, so that tip side can the 7c of occlusion of openings section at branching portion 8 places.In addition, opening/closing portion 6 is not limited to branching portion 8 places, also can be positioned on the 2nd stream B.
In addition, the tip side of opening/closing portion 6 is not contacted with the peristome 7c of channel member 7 and leans on the position of tip side than this peristome 7c, because not contact also is formed with the 1st stream A2 in the tip side of this opening/closing portion 6 and the 7c of ratio open section of channel member 7 by between the position of tip side.
Opening/closing portion 6 expands or contractive action according to the flow of the fluid R that flows in the 1st stream A1, A2.Namely, if as shown in Figure 2, with the 2nd control water 5a of section not under the contraction state of butt, the flow of the fluid R that flows in the 1st stream A1, A2 reaches more than the set amount, then can expand, and connect with the 2nd control water 5a of section as shown in Figure 4, and to keep inaccessible the 2nd stream B side of liquid-tight airtight state.
Below, use Fig. 1 that the method for the flow of controlling the fluid R that makes opening/closing portion 6 dilations is described.
As shown in Figure 1, the circulation port 156 of the cleaning and sterilizing groove 50 in the apparatus main body 200 of cleaning sterilizing device 100 utilizes circulation line 210 to be connected with each mouthful 133～135, at the medium position of circulation line 210, be provided with successively pump 221, flow transducer 240, CH valve 231 from the downstream.
In addition, on circulation line 210, be connected with an end of bypass line 211 between flow transducer 240 and CH valve 231, this bypass line 211 is provided with bypass valve 232 at medium position.In addition, the other end of bypass line 211 is connected with discharge pipe line 212, and an end of this discharge pipe line 212 is connected on the discharge outlet 155 of cleaning and sterilizing groove 50.In addition, be provided with drain valve 233, draining pump 222 at the connecting portion of the other end of the ratio bypass line 211 of discharge pipe line 212 by the position in downstream.
Therefore, at first, not use the 1st stream A1, A2 only to supply with in the situation of fluid R to ducts of endoscope 19 in the mode that can not leak from the 2nd stream B with fluid R, to close bypass valve 232 and to open the state-driven pump 221 of CH valve 231.
Its result, fluid R in the cleaning and sterilizing groove 50 from circulation port 156 via circulation line 210, from each mouthful 133～135 to cleaning sterilizing device connecting portion 3, throughput 2, blowing unit 4 flow, and supply in the ducts of endoscope 19 via the 1st stream A1, A2, peristome 11k.
At this moment, when the flow of the fluid R that flows in the 1st stream A2 reaches in the situation about setting more than the flow, as shown in Figure 4, opening/closing portion 6 expands because of the fluid R that flows in the 1st stream A2, and with the 2nd control water 5a of section liquid-tight airtightly butt, so fluid R does not flow to the 2nd stream B and only to ducts of endoscope 19 interior supplies.
Accordingly, opening/closing portion 6 is expanded and the situation of supplying with fluid R in the high-pressure wash of carrying out ducts of endoscope 19, comparatively applicable when having used the cleaning etc. of gas-liquid two-phase flow.
Then, in the situation that endoscope pipeline 19 and make fluid R leak to carrying out cleaning and sterilizing around tube head 11 and the tube head 11 from the 2nd stream B not only under the state of opening CH valve 231, is opened bypass valve 232.

Therefore, the situation the when flow of the fluid R that flows in the 1st stream A1, A2 is closed than bypass valve 232 reduces, and is less than the setting flow, and therefore, as shown in Figure 2, opening/closing portion 6 shrinks, thereby fluid R also flows in the 2nd stream B.Its result, fluid R also supplies to around the tube head 11.
Accordingly, make situation that opening/closing portion 6 shrinks except the cleaning and sterilizing that is applicable to common ducts of endoscope 19, also be applicable to when carrying out cleaning and sterilizing around tube head 11 and this tube head 11.
According to more than, by switching the switching of bypass valve 232, can make opening/closing portion 6 dilations.That is, only can switch in ducts of endoscope 19 and supply with or not only in ducts of endoscope 19, also around tube head 11, supply with.
In addition, the method for controlling the flow of the fluid R that makes opening/closing portion 6 dilations is not limited to the switching of bypass valve 232, also can be additive method.For example, also can use pump 221 originally just to make the fluid R quantity delivered of the 1st stream A1, A2 different.
So, in the present embodiment, in cleaning and sterilizing device for endoscope connecting device 1, be expressed as opening/closing portion 6 and the opening/closing portion 6 that periphery at the channel member 7 of the blowing unit 4 that is connected with the tube head 11 of endoscope 10 is provided with the flow dilation that is accompanied by fluid R and be positioned on the branching portion 8 or the 2nd stream B of the 1st stream A1, A2 to the 2 stream B.
Accordingly, in the situation that only to ducts of endoscope 19 interior supply fluid R, flow by the fluid R that will flow in the 1st stream A1, A2 is made as more than the set amount, opening/closing portion 6 is expanded and connect with the 2nd control water 5a of section and block the 2nd stream B, therefore can be only to ducts of endoscope 19 interior supply fluid R.
In addition, in the situation that not only in ducts of endoscope 19, also around tube head 11, supply with fluid R, flow set by the fluid R that will flow in the 1st stream A1, A2 is for being less than set amount, opening/closing portion 6 is shunk, thereby between opening/closing portion 6 and the 2nd control water 5a of section, produce the 2nd stream B, therefore can not only in ducts of endoscope 19, also around tube head 11, supply with fluid R via the 2nd stream B.
That is the simple structure that, can change with the quantity delivered that can make fluid R realizes that the dilation that whether is accompanied by opening/closing portion 6 blocks the 2nd stream B.
According to more than, a kind of cleaning and sterilizing device for endoscope connecting device 1, cleaning and sterilizing device for endoscope 100 with following structure can be provided: it can switch the situation of carrying out cleaning and sterilizing around the tube head 11 that carries out the situation of cleaning and sterilizing in the endoscope pipeline 19 only and not only go back endoscope 10 in the endoscope pipeline 19 and the tube head 11 with simple structure.
